What is static electricity?

In this lesson, we will be learning all about static electricity. We will learn how static charges occur and what happens when they are discharged. We will also be exploring how to create our own static charges with a balloon! If you have a balloon at home then you can use it for this lesson. If you don't then don't worry, you will still be able to watch the demonstrations and complete the lesson.
